How do you implement Basecamp style URL in Java/Java EE environment? eg <username>.hostname.com

Question

The Basecamp URL like .basecamphq.com, eg seymores.basecamp.com.

How can I do the same in a Tomcat environment?

Answer 1

Other aproximation is use UrlRewriteFilter. Using this filter with few policies you can, for example, convert calls like:

http://username.domain (before url rewriting)

to

http://domain/your_servlet?user=username (after url rewriting)
